I created a course (simple course with default features, not SCORM) and downloaded it. The extracted files are uploaded to the organization's internal server. When I access the course from the server link for the first time, initially the browser screen is blank for about 5-10 seconds and then the loading text and gif image appears. Sometimes, the 10-15 seconds duration is a bit longer and some of the users thinking that the course is not loading and they try to refresh the browser page. Is there any suggestions to avoid such experience?
